An engine for generating electricity that works on the principle of buoyancy

Abstract

This invention represents an environmentally friendly, highly efficient, and reliable engine that is a promising source of renewable energy. It operates on the principle of buoyancy in water. Storing energy in the form of compressed air is ideal, and combined with this engine, we have an economical energy storage system with high production capacity for electricity generation. It is possible to build a facility with many of these engines near wind turbines or solar cells. These energy sources are widespread in Germany, and they are used to power electric air compressors, store air in large tanks, and use this air to power these engines.The compressed air through this new engine can enable improved implementation of the energy and recovery process, especially during peak energy demand or in cooperation with conventional renewable energy sources such as wind and solar power, as well as ocean waves, to generate electricity simultaneously.

Description

Technical Description:➢ Previous Condition:

[0001] Renewable energy sources such as wind and solar power suffer from operational instability because they operate according to and depend on weather conditions. To ensure the stability of electricity production from these sources, it is necessary to store the energy from the renewable energy sources and feed it back into the grid when needed. In recent years, various ideas have emerged under the term energy storage, including those that use compressed air as a means of energy storage and reuse this air to spin a turbine. The idea of ​​storing energy in the form of compressed air makes sense in principle. However, consuming this air to generate electricity again results in significant air loss. For example, compressed air is used in some concepts to spin turbines, and these turbines are inefficient in terms of air consumption.They require large amounts of compressed air at high pressure and continuous pumping to operate these turbines and generate electricity. Additionally, increasing the power of these turbines is associated with an increase in rotor diameter, which means more compressed air is required.

[0002] There are ideas that utilize the principle of buoyancy by pumping air into submerged balloons suspended in a water tank. These balloons rise using the principle of buoyancy, and these balloons are attached to a metal chain and rotate approximately linearly. However, these models are rudimentary, impractical, and unbalanced. In these models, the balloons always remain at the same distance from the axis of rotation in both buoyancy and submersion states, which inhibits rotation and limits the torque and motor speed.

[0003] As is well known, the torque for such engines depends on the length of the balloon's support arm, the balloon's volume, and the number of balloons in the ascent cycle (lift). These conditions are not fully met in such designs.

[0004] On the other hand, air is pumped into containers or balloons and requires time to fill and deflate, which reduces the speed of these engines. Furthermore, the proliferation of air bubbles in the water poses a problem, and these bubbles have an opposite negative effect on the principle of buoyancy. The air bubbles significantly reduce the upward force of the balloons. ➢ Explanation of the invention

[0005] The subject of this patent application relates to a motor that rotates around a horizontal central axis. Several arms, ranging in number from 4 to 8, are evenly distributed around this axis. The length of each arm varies between 3 and 4 meters, which ensures torque due to the arm extension. Each arm carries an air-filled, tightly sealed, and as lightweight as possible plastic float (see Fig. , Part Number 1).

[0006] Here, the circular part of the motor rotates counterclockwise, meaning that all floats on the right side of the vertical are in the working cycle and are far from the center of rotation of the motor at the end of the arm. This motor is located in a tank made of reinforced cement with iron and is completely filled with water (see Fig. for the side view of the engine tank and Fig. for the front view of the engine tank)

[0007] The motor generates a torque proportional to the length of the float's support arm, the float's volume, and the number of floats to the right of the vertical that are in the water during the ascent cycle (buoyancy), in addition to the water density. The motor presented here meets all of these conditions to control the motor's torque, stability, and efficiency.

[0008] In this invention, the floats are driven and pulled by pistons powered by compressed air. This ensures high speed in moving the floats and thus a high rotational speed of the engine, something unattainable by other engines.

[0009] Because this motor I'm presenting here uses compressed air to drive the pistons and control the floats with these pistons, this means that air bubbles in the water tank are avoided. These bubbles have a negative and opposite effect on the principle of buoyancy and reduce the intensity of the water pressure on the floats. ➢ Engine parts: 1. The external tank: (see Fig. , Fig. , Fig. , number 26). 2. The floats: There are 4 pieces (see Fig. , Part Number 1). 3. The pistons: There are 4 of them (see Fig. , Part Number 2). 4. Compressed air regulator: There are 4 pieces (see Fig. , Part Number 27-7). 5. Valves for compressed air: There are 4 pieces (see Fig. , Part Number 28-6). 6. Ball bearings: (see Fig. , part number 9-8) and all similar symbols in the illustration. 7. Air leak preventer: (see Fig. , part number 19-18-11-10). 8.

Waterproof barriers: (see Fig. , part number 31-29-25-24-16-13). ➢ Explanation of the effective parts of the engine: 1. The tank:

[0010] The tank is the external structure of the engine and is made of reinforced cement with iron. Its diameter is determined according to the required capacity and can vary between 5 and 20 meters, while its width never exceeds 3 meters. It can be built either underground or above ground and can be square or circular. 2. The swimmers:

[0011] The float is a hollow and completely air-filled structure designed to reduce water turbulence and prevent the formation of whirlpools (see Fig. - Part 1). The floats are moved back and forth by a mechanism made of metal plates (see Fig. - Part 3). The function of these plates is to increase the piston stroke. The pistons used here are small, with a piston stroke length not exceeding approximately 15 cm. By using these plates, we can move the floats back and forth the required distance, allowing us to use small pistons to save air consumption and move the floats quickly.

[0012] On the other hand, this mechanism allows us to increase the length of the support arm for the floats, resulting in greater torque with lower air consumption from the compressed air tanks. This mechanism is repeated in each arm, from the piston to the plates for increasing the stroke, to the floats, and finally to the support arm of these parts. See Fig. showing the active components in each arm from the front view. 3. The pistons:

[0013] There are four pistons in this model, which are made of aluminum and operate with compressed air. Each piston has a forward and return stroke (see Fig. , Part 2). These pistons rotate with the rotating part of the engine and are attached to the circumference of the rotor (see Fig. , Part 21). The direction of the piston stroke is controlled by a small arm valve, which is moved by an eccentric cam on a fixed axis point that does not rotate with the engine (see Fig. , Part 20).

[0014] The eccentric cam releases the valve at the lowest point in the water and 10 degrees to the right of the dashed vertical (see Fig. , dashed vertical line, part 4). This pushes the piston and floats outward, away from the motor's axis of rotation. Note that the motor rotates counterclockwise in this case.

[0015] At the top of the water and 10 degrees to the right of the same dashed vertical line (part 4), the eccentric cam pushes the air valve arm to reverse the direction of the piston stroke. This pulls the floats closer to the motor's rotation axis before they reach the dashed vertical line (part 4), so they don't slow the motor to the left when crossing the dashed line.

[0016] The pistons take the compressed air from a channel within a fixed axis that does not rotate with the engine (see Fig. - Part 14). This axle is attached to the outside of the tank body with screws (17-12). The excess air pressure created by the alternation of the piston movements is discharged through the opening (34-30) of the valves, then through a hole in the fixed axle and finally from the water tank through opening 33. The air is pumped from the tanks into the engine through nozzle No. 15 (see Fig. ), and the air flows through the duct to the air distributor, indicated by the arrows. The air deflectors (19-18-11-10) prevent air from escaping, and each of the four pistons in the engine is connected to the air distributor via special plastic tubes.

[0017] Before the air reaches the pistons, it passes through a pressure regulator (see Fig. - Part 27-7). Each piston has its own pressure regulator, whose job is to ensure sufficient air flow to complete the process of pulling or pushing the floats with a minimal amount of compressed air. The pressure regulator also prevents the air pressure inside the pistons from reaching the level of the air pressure in the tanks, preventing overloading the pistons and minimizing the loss of compressed air. The priority here is to maximize air consumption.
